Kuwala zingwe: ubwino kuposa kuipa

Mu makumi asanu ndi awiri, zinali yapamwamba kwambiri ndi kuwala usiku kuchipinda, wopangidwa mwa pedestal hemispherical ndi chotuluka ku izo waveguides mtengo. Yomanga imeneyi mdima mdima kuunika ankalankhula mu mawonekedwe a madontho ang'onoang'ono, moto nsonga woonda ulusi translucent. Izi kwenikweni chinthu chokongola anapangidwa kuchokera muli a mtundu watsopano wa atsogoleri zambiri. Atchuleni - chamawonedwe zingwe (Aka - okhazikitsa, mwachitsanzo CHIKWANGWANI-chamawonedwe mizere kulankhulana).

FOL ntchito mfundo

Aliyense wochititsa magetsi ali ndi kukana osati yogwira, komanso zotakasika (capacitive ndi inductive). Izi magawo thupi amadalira awiri a waya, katundu yoweyula, ndi kumene mzere kutalika polumikiza chizindikiro sender ndi chipangizo kulandiridwa. Makamaka tcheru resistive khalidwe kulankhulana njira yapamwamba njira. CHIKWANGWANI-chamawonedwe chingwe alibe drawback ichi, zomvetsa laling'ono kwambiri kuposa ochititsa ochiritsira, chifukwa mudziwe chonyamulira ndi mphamvu ya kuwala. njira kanthu mfundo ndi zomveka bwino kwambiri. Link mbendera ndi athandizira, amatembenuka kuchoka zamagetsi ku kuwala. Pa kubwereketsa pali demodulation ake, ndipo akulowa chipangizo wolandila-mudziwe ali ndi chizolowezi voteji nyemba.

Ubwino CHIKWANGWANI Channel

Kuwonjezera kukana kuti chopinga ndiponso attenuation, zingwe kuwala ndi zina ubwino yofunika kwambiri. Pamene kufala kwa nkhani pa CHIKWANGWANI mitsinje sizivuta kulisunga zachinsinsi, chifukwa N'zosatheka kulumikiza ku mobisa. Ubwino wina kwa njira ya HIV ndi zachuma. Mkuwa - ndi zitsulo zodula ndi mtundu, mu zipangizo waveguide mtengo angakwanitse kwambiri. The chingwe kuwala amapangidwa khwatsi kapena nyimbo yapadera polima (fluoro-aluminate, kapena fluoro-zirconate), amenenso (ulemu chachitatu) ndi opepuka kuposa mawaya zitsulo kuyenela ndisanabadwe.

zolakwa kulankhulana kuwala

Inde, zingwe kuwala, komanso chirichonse mu dziko lino, si popanda zovuta.

Choyamba, kubwezeretsa kulankhulana ndi dera lotseguka amafuna m'malo a kuonongeka m'dera lonse, sakhoza spliced waveguides Choncho kwambiri kumawonjezera mtengo wa kukonza.

Kachiwiri unsembe ntchito ndi si mtengo wotchipa. Awo kukhazikitsa ayenera makina cholondola, ndipo ndi okwera mtengo. Ndipo luso chofunika ndithu, ndipo akufunika ndi kulipira mogwirizana.

Kachitatu, kuti anati chizindikiro Converter pa athandizira ndi linanena bungwe mizere, komanso zolumikizira (zipangizo zofunika kusinthitsa), kwambiri zofuna kudalirika zomvetsa kuwala molondola. Kuti khalidwe m'pake ndalama, palibe amene akufuna kufotokoza.

Communication tsogolo

Komabe, ubwino kwambiri. Kuwala zingwe angathe kupereka burodibandi chizindikiro chimene kwambiri kumawonjezera liwiro kuwombola mudziwe (anayeza kale mu terabits pa wachiwiri). Pamene attenuation imeneyi ndi yaing'ono kwambiri (pa munthu timaganiza za 1,55 microns, ndi DB 0,22 okha / km). Komanso, luso mafunde kuwala kusuntha mbali zosiyana (ndi zosiyana kugawanika) mmodzi CHIKWANGWANI chamawonedwe wochititsa kumawonjezera mwayi. kusintha awo ukupitirira.
